Abstract:
Disclosed is the addition of passive feedback to a prior art T. sup. 2 L circuit. The T. sup. 2 L circuit with feedback, in accordance with the invention, has a lower power dissipation while retaining noise immunity and small gate delay. The additional resistor required for the feedback T. sup. 2 L circuit, in accordance with the invention, can be incorporated into the T. sup. 2 L cell without increasing the cell size. The feedback T. sup. 2 L circuit, in accordance with the invention, lends itself to the addition of an integrated direct-coupled inverter (DCI) function. The feedback T. sup. 2 L circuit, in accordance with the invention, permits more function to be placed on an integrated circuit semiconductor chip while maintaining gate performance and adherence to power restrictions.
